GAS ANALYSIS APPARATUS, Portable Orsat, for the determination of CO 2 , CO and O 2 . This 

 instrument is very light and compact, having only half the weight and one fourth the volume 

 of the usual form, and can be shaken bodily during an analysis, thus increasing the rapidity 

 of the absorption. Complete with three absorption pipettes of special form, water jacketed 

 measuring burette with stripe to facilitate reading, manifold with four stop-cocks, filtering 

 tube, aspirator bottle and rubber bags, mounted on metal stand with metal cover. Height 

 over all, 15 inches; diameter, 5% inches; total weight charged ready for use, 6 pounds.. 27.50 



GAS ANALYSIS APPARATUS, Portable Orsat, same as No. 6652, but with only two absorp- 

 tion bulbs, for CO 2 and O 2 $25.00 



GAS ANALYSIS APPARATUS, same as No. 6652, but with four absorption bulbs, for CO 2 , CO,

ASPIRATING PUMP, for use with Nos. 6652, 6654 and 6656 1.00 



GAS ANALYSIS APPARATUS, Portable Boiler Tester, for determining the draft and percent- 

 age of CO 2 in flues. Consists of a special measuring burette which is also used as a draft 

 gage, an absorption pipette of special form filled with glass tubes, filter tube and leveling 

 bottle, mounted on metal stand with metal cover. Height of case, 14 inches; diameter, 5 

 inches; weight, 4 pounds 17.50 



GAS ANALYSIS APPARATUS, United States Steel Corporation Official Type, as designed by

 with water-jacketed measuring burette, manifold tube with two stop-cocks, four pipettes with 

 stop-cocks, two leveling bottles, pint Kipp's generator, two 2 liter and one 4 liter aspirator 

 bottles, overflow bottle for explosion pipette, rubber bags, and metal sampling tube with 

 brass stop-cocks, mounted on hardwood stand, with directions for use. (See Metallurgical 

 and Chemical Engineering, Vol. IX, 1911, page 303; and "Methods for the Technical Sam- 

 pling and Analysis of Gases, ' ' of the United States Steel Corporation) 80.00
